The fittest is the organism that can survive where others cannot dare survive.
Natural Selection: survival of the fittest
Some traits are accidental. Genetics have an element of random variation whether by the recombination of genetics that comes with sexual reproduction, or by mutation, and while some changes can be selected for or selected against by the evolutionary pressure described as "survival of the fittest" there are also changes that make little if any difference to the survival of the organism or of the species, and so, they are not subject to evolutionary pressure. Therefore they are not adaptations, they are just accidents.
a. they help the organism survive in its environnment .
true
No adaptation, no survival. Hence: Darwinism, evolution, survival of the fittest.
The fittest is the organism that can survive where others cannot dare survive.
Survival of the fittest mean the organism that is reproductively fit. The organism that survives, but more importantly, outproduces conspecifics in progeny id the fittest.
Natural Selection: survival of the fittest
Camouflage and protective coloring adaptations improve an organism's chances of survival and reproduction.
The two kinds of adaptations an organism can have is a behavioral or a physical adaptation. These both help the organism survive.
Traits that enable an organism to survive and reproduce are known as adaptations. Each organism has specific adaptations suitable for its environment.
Adaptations work by allowing an organism to adjust and change so that they can survive in a changing environment. This allows the organism to live longer.

They enable them to survive.
Adaptations
Natural selection (survival of the fittest) means that valuable adaptations and mutations have the greatest number of surviving descendants.
